摘要： A primary piston (19) slides axially on a spindle body (5). Together with two cylindrical bearing surfaces of different diameters (D1 and D2) of the spindle body, the primary piston bounds a primary hydraulic chamber 22) which communicates via a conduit (25) with a secondary hydraulic chamber (24). The active face (33) of a secondary piston (20) bounds the secondary hydraulic chamber (24), so that the secondary piston (20) is displaced in response to a displacement of the primary piston (19) which is reduced in the same ratio as the cross-sections of the two chambers. The secondary piston (20) acts upon a chucking sleeve (15) which actuates the chuck (12) against the bias of a spring member (17) which, in the absence of pressure, holds the chuck (12) grippingly on a workpiece. The primary piston (19) is controlled by compressed air fed through a fixed spindle support (1) via a conduit (27) into a pneumatic chamber (21) bounded by a fixed bore (8) and by two disk-shaped elements (7 and 19) rotating with the spindle.

摘要： An electric motor can drive a workpiece and a tool simultaneously at speeds in a ratio adjustable at will. The workpiece is driven via two pulleys and a belt, while the tool is driven via further pulleys and a belt from a hydraulic circuit comprising a pump coupled to the electric motor and a hydraulic motor. The pump is preferably of the variable-capacity type so that its flow can be modified independently of the speed of the electric motor.

摘要： Automatically controlling the transmission ratios of an automotive vehicle engine by detecting the speed of the engine, generating a signal proportional to the detected speed and comparing this signal with different predetermined reference speed signals, detecting the transmission ratio of the transmission, comparing this ratio with a predetermined reference ratio and generating a ratio signal as long as the detected ratio remains below the reference ratio, maintaining the detected ratio constant until the detected engine speed signal falls below the predetermined reference speed signal and generating a signal to increase the transmission ratio when the engine speed signal falls below the predetermined reference speed signal, and increasing the transmission ratio in the direction of the reference ratio as long as the detected speed signal remains below the predetermined reference speed signal and the detected ratio is less than the reference ratio.

摘要： A machine tool spindle bearing assembly employing front and rear bearings each having radially compressed rolling elements between an inner race press fitted on the spindle and an outer race press fitted into a section of a thermal adaptor mounted on the spindle housing through a heat barrier section. The combined masses of each outer race and the section of the thermal adaptor supporting the outer race are related to the total mass of the rolling elements of the bearing so that, in response to the heat generated by the rolling contact forces between the rolling elements and the outer race, the mean diameter of the track of the outer race increases to twice the increase in diameter of a rolling element. The thermal barriers of the thermal adaptors are radially rigid; the thermal barrier of the front thermal adaptor is axially rigid and the thermal barrier of the rear thermal adaptor is axially flexible.
